Answer:
x = 9
Step-by-step explanation:
0.09+27/100=x/100+27/100
0.09=x/100
9=x
Let's solve your equation step-by-step.
25812−4.2d=31.311−5.5d
Step 1: Simplify both sides of the equation.
25812−4.2d=31.311−5.5d
25812+−4.2d=31.311+−5.5d
−4.2d+25812=−5.5d+31.311
Step 2: Add 5.5d to both sides.
−4.2d+25812+5.5d=−5.5d+31.311+5.5d
1.3d+25812=31.311
Step 3: Subtract 25812 from both sides.
1.3d+25812−25812=31.311−25812
1.3d=−25780.689
Step 4: Divide both sides by 1.3.
1.3d
1.3
=
−25780.689
1.3

Answer:
No
Step-by-step explanation:
Use the vertical line test, you can conclude that this is not a function.
Answer:
Step-by-step explanation:
Y = mx + b
slope(m) = 3/4
(3,7)...x = 3 and y = 7
now we sub...we r looking for b, the y int
7 = 3/4(3) + b
7 = 9/4 + b
7 - 9/4 = b
28/4 - 9/4 = b
19/4 = b
equation is : y = 3/4x + 19/4...lets put this in standard form
y = 3/4x + 19/4
-3/4x + y = 19/4...multiply by -4
3x - 4y = -19 <== standard form
if (x,5) is on the line
3x - 4y = -19.....sub in 5 for y
3x - 4(5) = -19
3x - 20 = -19
3x = -19 + 20
3x = 1
x = 1/3 <====so point a = (1/3,5)
Answer:
the answer is 25
Step-by-step explanation:
45+30=100-w
then your going to subtract 45 on both sides. So 100-45 is 55.
so now your equation looks like this
30 = 55 - w
subtract 55 on both sides so you will have -25 = -w. Then your going to divide -w on both sides and you will have positive 25
i hope thus helps
